SIGNALING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 530,236, dated December 4, 1894.

Application filed February 18, 1 890. Serial No. 340,935. (No model.)

To all whom it may concern: phones are connected in the signaling circuit Be it known that I, BERNIOE J. N OYES, of from the street boxes to the central station Boston,c ounty of Suffolk, State Of Massachuand the ordinary magneto-call employed. setts, have invented an Improvement in Sig- This invention also comprehends the em- 5 naling Apparatus, ofwhich the following deployment of particular means for-carrying 55 scription, in connection with the accompanyout the several results. ing drawings, is a specification, like letters on Figure 1 shows in diagram a signaling cirthe drawings representing like parts. cuit and instruments therein constructed and United States Patent No. 359,688, granted arranged to-carry out the results embodying to to me March 22, 1887, shows and describes a this invention; Fig. 2,a front view of asignal 6o signaling apparatus especially adapted for box which may be employed in carrying out police signaling purposes wherein multiple this invention. signal transmitters are arranged in boxes at Referring to Fig. 2, the signal box comprises different points along the streets, and cona shell or case (1, having a face plate I), and

The signal box also contains telea means for eifecting such difierentiation, the phonic instruments such as a transmitter 25, impulses transmitted vary in length of durareceiver t, and a magneto-call t tion, that is, some signals comprise a series In the diagram, Fig. 1, the signal boxes are of short changes and others comprise a long represented at S.

station and all the wagon calls are received Atthe wagon house or auxiliary station (1 at the wagon house direct, while a bell or a relay 0 is includedin the circuitfthe armaother indicating signal is located at; the centure o of which when retracted closes alocal tral or receiving station to respond to the circuit 0 containing a local battery 0 a re wagon calls. 1 corder o, and a bell or other indicator 0 5o Alsoin accordancewith this inventi loo As it is desired that the relay 0, shall be effected only on the occurrence of the wagon calls, some means of distinction must be employed, and for simplicity, I have herein em ployed as a distinguishing impulse one of long duration in contradistinction to those of short duration, and the armature-bar has, or is secured to, a toothed sector 0 with which cooperates a pallet 0 Upon the occurrence of an impulse of long duration, the armature 0' receding with a slow movement owing to the action of the retarding device shown, will strike a contact 0*. Owing to the construction of the retarding device, the armature 0' will also be attracted slowly, and hence when against the contact 0 will vibrate back and forth opening and closing the local circuit 0 so that as a series of short impulses follow the long or distinguishing impulse, the recorder 0 and bell 0 will respond. One of the instruments 0 or 0 maybe omitted.

The local circuit 0 extends from the wagon house or auxiliary station d to the central station e, and at the last-named station, a bell to or, it may be, a visual indicator or other receiving instrument is included in said local circuit sothat as the recorder o or bell 0 operate, the hell or indicator u will respond and indicate at the central station the wagon signals. This local circuit connecting the wagon house or auxiliary station with the central station is an important feature, because it is absolutely necessary that the attendant in charge at the central station should know when the wagon calls come in, to determine when and where the wagon is called, and by arranging the bell in the same circuit with the receiving apparatus at the wagon station, and thereby controlled by the same circuit changing device which controls the instruments at said wagon house it is safe to conclude that when the bell at said central station is operated, the receivinginstruments at the wagon house, are also operated; and furthermore as the receiving instruments at the wagon house are operated. directly from the boxes, there is no liability of mistakes on the part of the attendant in charge, who now repeats them.

I claim- 1. In a police signal system, signal boxes, each containing a multiple signal transmitting apparatus, constructed and arranged to transmit difierent signals and to produce distinguishing impulses with some and not with others; a central station; a receiving apparatus thereat in circuit with and to receive all the signals transmitted by said signal transmitting apparatus; combined with a distant auxiliary station; a circuit changing device thereat controlled by said circuit and operated by said distinguishing impulses; a telltale local circuit controlled by said circuit changing device and leading from the said auxiliary to said distant central station; and an indicating device in said local circuit at said central station to indicate at the latter the reception of a signal at the distant former station; and a signal receiving instrument at said auxiliary station and responsive to signals transmitted by said signal transmitting apparatus, substantially as described.

2. In a police signal system, signal boxes, each containing a multiplesignal transmitting apparatus, constructed and arranged to transmit different signals and to produce distinguishing impulses with some and not with others; a central station; a signal receiving apparatus thereat in circuit with and to receive the signals transmitted by said signal transmitting apparatus; combined with a distant auxiliary station; a circuit changing device thereat controlled by said electric circuit and set in operation by said distinguishing impulses, and thereafter operated by and responsive to the regular impulses of signals transmitted; a tell-tale local circuit controlled bysaid circuit changing device and leading from said auxiliary'to said distant central station; a signal receiving instrument at said auxiliary station and controlled by and responsive to changes inthe condition of said local circnit;.and a tap bell alsoin said local circuit but locatedat the said central station to tap the box number at the latter station simultaneously with its reception at the distant auxiliary station, to indicate at the former proper reception of the signal at the latter, substantially as described.

In a police signal apparatus, signal boxes, each containing a multiple signal transmitting apparatus, constructedand arranged to transmit different signals and to produce distinguishing impulses with some and not with others; a central station; a receiving apparatus thereat; a relay controlling the circuit of the said receiving apparatus and in circuit with said transmitting apparatus, combined with a distant auxiliary station, a circuit changingdevice'thereat also in said circuit andresponsive first to said distingnishingimpulses only, and thereafter to the regular i1npulses of signals transmitted, a local circuit controlled by said circuit changing apparatus and containing a signal receiving instrument located at the auxiliary station; and an audible alarm device located at the distant'central station, whereby only special signals distinguished by said distinguishing impulses are received at said auxiliary station and their reception made known bysaid audible alarm at the distant centrahstation, substantially as described. h

4. In a signalingapparatus, a main signal ing circuit connecting street boxes, a central station, and a wagon" house, a receiving instrument at the receivingfstation (for receivin g all signals, cdm'binedwith a receiving relay at the wagon .honse, a'retarded armature therefor, a local circuitcontrolled by said retarded armature, and two receiving instruments in said local circuit, one at the wagon house, and the other at the central station, substantiallyas described.

5. In a signaling apparatus, a main signalrao and one at the central station, substantially as described.
